 watery moiflure when thus expofed to the weather,

 gutters cannot be very wholefome or eligible for 

 internal ufe; yet where fprings are fcarce, the in- 

 habitants are obliged to have recourfe to rain-water 

 for all domeflick purpofes. Nor will the painted 

 coating, confifling of coal pitch, lately propofed for 

 obviating this inconvenience, be likely to fucceed, 

 but rather to increafe the evil, efpecially as it con- 

 tains a manifeft acid : and were white-lead paint to 

 be ufed in its (lead, the remedy dill would be worfe 

 than the difeafe. 



Copper, ^moreover, being a powerful conductor of 

 eledricity, might not fuch a wide-extended furface 

 of infulated metal, aided by iron pallifadoes around 

 the parapets, tend to invite the lightning in a fcvere 

 thunder ftorm, and accumulate it, fo as to fhiver 

 the whole building to atoms?
